I put my Silverado today on the dyno and It gave me shitty numbers Didnt expect that from a tuned Silverado



Mods: Tune & S&B intake This is the run before the cam and converter I will post the cam and verter after 1 month havent recieved them yet.

The truck has no problems with Regular cabs w/4.10 gears as long as it is from a roll.

 

what size rims and tires are you running and what gears?

 

17" Factory rim and 3.73 gears

 

Only the track will tell, dynos are funny and will all spit out different numbers for the same setup, there are too many variables

 

Damm I Think You Should Have More Than That With A Tune And Cold Air.a Stock 2008 4.8 Threw 230 Rwhp-stock-.

 

From what I gather the Dyno Dynamic dynomometers read very low in comparison to the others. More in-line with MDs. Dyno #'s are good for reference to mods, like you add these mods and re-tune, dyno and see how much you gained. That and as an actual tuning tool, like what 95 BT said, the track is the only honest measure of true power.

 

I wouldn't worry about it. My tuned 6.0 only put down 267/296. It's just the dyno.

 

Thats what a tuned ls1 gto gave us today its the exact same numbers

 

I have seen trucks that do not put down great numbers and run awesome at the track and trucks that put down great numbers and run like crap at the track
I am a believer at what they run at the track not dyno numbers

 

ya something is wrong there. I put down 250rwhp with just CAI and muffler. and then 277rwhp after the tune.
